PRODUCT INFORMATION
Product Overview
The Bently Nevada 2300/20-00-00 is a dual-channel Vibration Monitor within the Bently Nevada 2300 series machinery protection family. It delivers continuous machinery monitoring and asset protection for critical industrial rotating equipment. The monitor processes signals from accelerometers, velocity sensors, or proximity transducers using independent 24-bit analog-to-digital converters.
This hardware unit operates from an input power range of 18 to 36 VDC with 7.5 W consumption. It provides two dry-contact SPDT relays alongside two configurable 4 to 20 mA outputs. The monitor features three buffered BNC outputs for vibration and speed analysis. Communication occurs over Modbus Ethernet using an integrated 10/100 Base-T RJ45 port.
